Glad to announce LDC 1.11:

* Based on D 2.081.2.
* Prebuilt packages now using LLVM 6.0.1 and including additional 
cross-compilation targets (MIPS, MSP430, RISC-V and WebAssembly).
* Rudimentary support for compiling & linking directly to 
WebAssembly. See the dedicated Wiki page [1] for how to get 
started.
* AArch64 (64-bit ARM) now mostly working on Linux/glibc and 
Android.
* Some support for classes without TypeInfos, for -betterC and/or 
a minimal (d)runtime.

Awesome news! Will we get a release of the ltsmaster branch as 
well? From the release notes it sounds like building with a more 
recent version is a good idea...

Using latest ltsmaster is always a good idea. I'm a bit reluctant 
to tag a new version, as it's a moving target (e.g., needed 
another adaptation yesterday in order to be able to bootstrap 
2.082-based LDC, and will need more adaptations in a few weeks 
for LLVM 7...). 0.17.6 has been stuck in the pipeline for half a 
year now; perhaps we finally manage after LLVM 7 is supported.

The thing is, a release is actually tremendously helpful for the 
Debian packaging - we are using the latest tagged version there 
for ages.
I could, if you think that it is a good idea, just use a snapshot 
of the current ltsmaster Git branch, but that makes it harder to 
track with which ltsmaster state the Debian package was actually 
built with.

That'd be no work for us, so I'd clearly prefer it this way. ;)

The used host compiler, incl. git hash if untagged, can be found 
in the --version output:

```
LDC - the LLVM D compiler (1.12.0git-1c87fd7):
   based on DMD v2.082.0 and LLVM 6.0.0
   built with LDC - the LLVM D compiler (0.17.6git-79d2284)

Does that Git has thing work if there is no Git involved? ;-)
To make this work I will have to download a tarball of ltsmaster, 
with no Git involved to get the hash from.

Ewww, looks like I can't write today...
At the moment, we get
```
LDC - the LLVM D compiler (1.8.0):
   based on DMD v2.078.3 and LLVM 5.0.2
   built with LDC - the LLVM D compiler (0.17.5)
```
unconditionally - if I switch to a ltsmaster snapshot, it will 
likely display 0.17.6 with no direct way of knowing which 
snapshot was taken.
(I could manually record that as an info file in the package, so 
it at least is recorded somewhere, but that's not easily 
accessible at all...)

Hope is good, contributing better. ;) AArch64 needs polishing, 
wading through the logs and analyzing & fixing (or 
disabling/adapting unfitting tests) the remaining test failures.

As to RISC-V, I don't think there's any library support at all 
right now, so there's probably still a long way to go for 
something close to being usable. Claiming (and maintaining) 
production-readiness requires a CI service for RISC-V.

Who is actually running AArch64 or RISC-V in a "production 
environment?" Maybe a few for AArch64, but pretty much nobody for 
RISC-V. I tried looking for a RISC-V VPS or dev board recently 
and found basically nothing, just two boards from SiFive that are 
too small or too expensive.

I've actually heard of it, what of it? Is someone using it in a 
production environment, or do they have a VPS or dev board? If 
not, academic projects sitting half-finished in some grad 
students' computers somewhere aren't relevant to my questions.

Since this is the first ldc release with a mostly working 64-bit 
ARM, ie AArch64, port, I've put up ldc builds for linux/AArch64 
and Android. You can get the linux build at the github link 
above; the Android build is available from the Termux app in the 
Android store, by running `pkg install ldc`:

https://play.google.com/store/apps/details?id=com.termux&hl=en

You can see what else remains to be done for the AArch64 port by 
looking at the logs from the linux/AArch64 Shippable CI linked 
from the github release and the checklist in this ldc tracking 
issue:

https://github.com/ldc-developers/ldc/issues/2153

I've added info on how to cross-compile a D runtime and standard 
library for linux/AArch64 to the wiki:

https://wiki.dlang.org/Building_LDC_runtime_libraries#Usage_for_cross-compilation

I've also started updating the wiki on how to build Android apps 
in D for 64-bit ARM devices.
